Pada gambar segitiga dibawah ini, panjang KL = b = 12 cm, KM = ML = a = 10 cm, dan MN = c = 8 cm, maka kelilingnya adalah ....
Explanation
The perimeter of the triangle is calculated using the formula K = 2a + b. In this case, a is given as 10 cm and b is given as 12 cm. Plugging these values into the formula, we get K = 2(10) + 12 = 32 cm. Therefore, the perimeter of the triangle is 32 cm.Rate this question:

Pada gambar segitiga dibawah ini, panjang KL = b = 12 cm, KM = ML = a = 10 cm, dan MN = c = 8 cm, maka luasnya adalah ....
Explanation
The formula to calculate the area of a triangle is 0.5 x base x height. In this case, the base (b) is given as 12 cm and the height (c) is given as 8 cm. Plugging these values into the formula, we get 0.5 x 12 x 8 = 48 cm. Therefore, the area of the triangle is 48 cm.Rate this question:

Segitiga ABC mempunyai panjang AB = ( 2x - 1 ) cm, BC = ( x + 5 ) cm, dan AC = 3x cm, sedangkan kelilingnya = 46 cm, maka panjang AB adalah ....
Explanation
The given explanation solves for the value of x by setting up the equation for the perimeter of the triangle, K = (2x - 1) + (x + 5) + 3x. It then simplifies the equation and solves for x, which is found to be 7. Finally, it substitutes the value of x into the equation for AB to find the length of AB, which is 13 cm.Rate this question:

Segitiga ABC siku - siku di A mempunyai panjang AB = ( 3x - 11) cm, BC = 20 cm, dan AC = 12 cm, sedangkan luasnya = 96 cm persegi, makanilai x adalah ....
Explanation
The given explanation shows the steps to find the value of x in the equation. It starts by using the formula for the area of a triangle, which is ½ x base x height. The base (AB) is given as (3x - 11) cm and the height (AC) is given as 12 cm. The area is given as 96 cm^2. By substituting the values and simplifying the equation, we can solve for x. The final answer is x = 9 cm.Rate this question:

Segitiga ABC, Dengan panjang AB = 4 cm, BC = 6 cm, dan AC = 8 cm , maka luas segitiga ABC tersebut adalah ....
Explanation
The given solution calculates the area of triangle ABC using the formula for the area of a triangle, which is 1/2 * base * height. The length of AB is given as 4 cm, BC as 6 cm, and AC as 8 cm. The formula for the area is then simplified to 1/2 * 6 * 8, which equals 24 cm^2. However, the given solution calculates the area incorrectly by using a different formula and arrives at the answer of 11.6.Rate this question:
